Blade Attila video: • The cheapest & easiest...

[@thehumbledabbler]

Thank you so much for actually taking the time to narrate these instructions, rather than make the viewer either read (I'm watching a video, I don't want to read, otherwise I'd read one of the millions of articles on this subject) or interpret a bunch of hand gestures, (never been good at cherrades). Bravo. Liked, and subscribed.

Good to see how the basic instructions goes to viral around the world! Thanks for your adaptation! I'm so happy with it! BLADE

Thanks Blade! I will keep working on this 👍

🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

[@frankgiancola7]

After I build that amazing Stirling with the great instructions from Atila Blade I too didn't know how it worked. Thinking about it over and over again I think this is how that stirling engine works.The piston moves upwards when hot (expansion ) and downwards when cool ( contraction ) The heat source heats the bottom of the can and heat is transferred to air above it slowly by convection as displacer reaches bottom hot air is transferred to upper air above displacer creating a pressure moving the piston upwards and the heat is transferred to the air instantly radiantly when air pressure increases density of air to than that more of the balloon. On the downstroke pressure decreases to less than that of rubber and heat is transferred radiantly instantly back to the air. Radiant heat transfer is instant and heat transfer due to convection is very slow. Heat travels radiantly towards a denser mass and will not travel in the opposite direction. Conventional heat transfer only occurs in the upwards direction. I hope this helped. Good video as usual Mr ludic.

[@ludicscience]

Well let me think about it

[@macrumpton]

Nice simple video of the construction. I wonder if having the cut on the outer can further down the side so there is more cooling area, and maybe a little insulation between the hot end and the cold end would make it run even better.

[@joekavanagh5708]

The power cylinder should be smaller ~1/5 of the displacer cylinder. It depends on the temperature difference.

[@bjetTube]

This is a simple and great explanation of the unit. Awesome job!!!

[@KipIngram]

FANTASTIC demo. Very nice, my friend.

[@trench01]

For you everything is easy to make LOL. To find the optimum weight maybe use a spring on the top and adjust it to see how much pressure is needed and translate it to weight.

[@ludicscience]

That is a good idea

[@vid2ification]

Followed instructions perfectly but it doesn't work because I couldn't find kiwi strawberry and green tea flavors and used a pepsi. This was the problem because in the second attempt I made the engine with an energy rx and arnold palmer light for more power and weight reduction, respectively. Then I replaced the pepsi with coke i got from a guy at the skate park. The engine now produces unfathomable amounts of power and agility, but really drags after a while and begins to randomly backfire for no apparent reason. I wonder if there is a facility I can send it to for some tuning so it may perform in a more balanced manner for longer periods of time.

[@Lucas-CT]

very good, I'm getting fascinated with these engines. I will try to make one of those you showed. but came up with the idea of using one of those aliexpress low temperature stirling engine made for coffee mug.. on the backplate of my video card, putting fan blades on the rotating part .. the intention would be to have something interesting inside the computer visible through the case window .. I imagine it would not have much efficiency in cooling the computer, but would help dissipate the heat of the board (witch gets up to 75C) by having a metal base and a little air circulation with the fan blades in place of the wheel. it would be easier with a simple normal cooler fan, but not as nice lol. a "free" energy fan.. You could try a video using one of these, I think it would be interesting.

[@christomold3142]

It is easy to understand. Displacer piston is moving to hot and cold side and doing all the work (pressure expand and shrinks). The "power" piston is not making any work. It is only to make resonance (to make it 90deg later in standard srirling engine). It is also keeping displacer in move. Youre welcome.

[@davidvea4850]

Fine! Keep the good work man

[@Edmorbus]

Great project

[@anandawijesinghe6298]

An explicit regenerator implementation is missing in this version of the Free Piston Strirling Engine.

[@macrumpton]

I think the thin heat conducting walls of the displacer probably add some of that function back.

[@w0mbhanger]

it works on rise n drop pressure right? everytime it goes further from flame pressure drops back down the can cools so fast huh? or it sucks in air from the holes or both? i guess a little both but doesnt this model rely on holes n cover it up no worky?

[@nonothebot]

Strange ! I think the upper part of the can acts like cold rad, but the tape is too large and the heat cannot evacuate properly ; try to put a narrower tape so that the rad works better.

[@ludicscience]

Yes that is good idea

[@aznative_]

Or use aluminum duct tape

Hey ludic science, I have made the wireless energy transfer device that u showed 4 years ago and was astonished to find that if u turn the coil upside down(180 degrees) it gives less or greater voltage! I made the circuit various times and with different types and turns of coils....all supporting this theory....but I am still confused. It might be somewhere my error that I can not seem to find.... I don't own an oscilloscope so I am hoping that u can confirm my experiment and possibly give an explanation. Thanks a lot... Love ur vids...

[@ludicscience]

Hi, I think the air signals that you are receiving are not symmetrical and that is the reason you get different voltages depending on orientation, to confirm that you need an oscilloscope....

I have a homemade alcohol burner just like that I’m using, and I have it set about 2 1/2 inches above the burner on a metal grate, and the flame is touching the can quite a bit.
